1550650 and Serial No. 22755 with Type ST-202 AC GM HEI Adapter Part No. 1550877 with Serial No. 790167199 Manufactured by Kal-Equipment Company out of Ostego, Michigan 49078. It also has an exhaust machine that has UL AC 12V 40870 stamped on some internal parts along with a timing gun, plastic pliers, some wiring harnesses & connectors/adapter harnesses, a couple of unidentified metal pieces and any of the other pieces you may see in the pictures. It also comes with the red AC Delco Cover as well. It says it is produced exclusively for AC Spark Plug Division. It has a harness hook-up diagram for engine analysis on the back side of it. I don’t have any literature with it so there is no user’s manual or anything but you may be able to find it some where. It does work so you could use it or it would make for a great display item some where like a shop, garage, man cave or any where else you can think of. It is pretty cool looking. I think I covered anything if you have any questions let me know. Condition: Very nice to excellent overall condition. Some paint issues here and there throughout, minor rust, scuffs, scratches but the main display part with all of the knobs and displays is in excellent condition as well is everything else included. The AC Delco Spark Plug Cover is also in very nice to excellent overall condition with just some minor things going on there is 1 minor slit on the 1 side that is a few inches long but it doesn’t go all the way through its just on the outer layer. I did not know how to test everything but I did hook It up to a battery and as you can see in the one picture it does work the lights lit up in all 3 sections for me and my dad’s mechanic did hook it up to a car but he didn’t know how to use everything but everything we did try it worked so I would say everything looks like it should work. 1 small short skinny cord has the coating falling apart a bit. Sat in storage many years not being used at a speedometer repair shop not being used. Very nice to excellent physical/cosmetic condition with some paint and rust issues here and there and mechanically in great working condition. Would make for a very cool retro display in a shop, garage or man cave. I have many more pictures if you want to see any more areas or close ups let me know. See pictures for further details on condition and to see what you are getting. The top should come off and the wheels should come off but I think the rest of it is stuck together with rivets.
